Phenotypic characteristics of human type II alveolar epithelial cells suitable for antigen presentation to T lymphocytes

open access: yesRespiratory Research, 2011
Background Type II alveolar epithelial cells (AECII) are well known for their role in the innate immune system. More recently, it was proposed that they could play a role in the antigen presentation to T lymphocytes but contradictory results have been ...

Immunosuppression Reversal Nanovaccines Substituting Dendritic Cells for Personalized Cancer Immunotherapy

open access: yesFrontiers in Immunology, 2022
Although immunotherapy has paved a new avenue for cancer treatment, inadequate immune response often executes suboptimal therapeutic effects. In general, an effective immune response undergoes presentation of antigen by antigen-presenting cells ...

Antigen - presentation by vascular endothelium : its role for CTL - mediated vascular injury [PDF]

open access: yes, 2008
Background: EC express and present MHC class I restricted peptide antigens and due to the exposed position may be targeted by antigen-specific CTL. We wished to explore the type of vascular injury that is mediated by peptidespecific CTL in vivo when EC ...

B7 costimulation molecules encoded by replication-defective, vhs-deficient HSV-1 improve vaccine-induced protection against corneal disease. [PDF]

open access: yesPLoS ONE, 2011
Herpes simplex virus 1 (HSV-1) causes herpes stromal keratitis (HSK), a sight-threatening disease of the cornea for which no vaccine exists. A replication-defective, HSV-1 prototype vaccine bearing deletions in the genes encoding ICP8 and the virion host

The role of ICOS in the development of CD4 T cell help and the reactivation of memory T cells [PDF]

open access: yes, 2007
We have addressed the role of the inducible costimulator (ICOS) in the development of T cell help for B cells and in the generation, survival and reactivation of memory CD4 T cells and B cells.

B7-1 and B7-2 Have Overlapping, Critical Roles in Immunoglobulin Class Switching and Germinal Center Formation [PDF]

open access: yes, 1997
Humoral immune responses were characterized in mouse strains lacking either or both B7 molecules. Mice deficient in both B7-1 and B7-2 failed to generate antigen-specific IgG1 and IgG2a responses and lacked germinal centers when immunized by a number of ...

Structure and dimerization of a soluble form of B7-1 [PDF]

open access: yes, 2000
B7-1 (CD80) and B7-2 (CD86) are glycoproteins expressed on antigen-presenting cells. The binding of these molecules to the T cell homodimers CD28 and CTLA-4 (CD152) generates costimulatory and inhibitory signals in T cells, respectively.

The Role of Co-inhibitory Signaling Pathways in Transplantation and Tolerance

open access: yesFrontiers in Immunology, 2012
Negative costimulatory molecules, acting through so-called inhibitory pathways, play a crucial role in the control of T cell responses. This negative ‘second signal’ opposes TCR activation and leads to downregulation of T cell proliferation and promotes ...

High-throughput sorting of the highest producing cell via a transiently protein-anchored system. [PDF]

open access: yesPLoS ONE, 2014
Developing a high-throughput method for the effecient selection of the highest producing cell is very important for the production of recombinant protein drugs.

Clinical Insights Into Novel Immune Checkpoint Inhibitors

open access: yesFrontiers in Pharmacology, 2021
The success of immune checkpoint inhibitors (ICIs), notably anti-cytotoxic T lymphocyte associated antigen-4 (CTLA-4) as well as inhibitors of CTLA-4, programmed death 1 (PD-1), and programmed death ligand-1 (PD-L1), has revolutionized treatment options ...
